10 USE INSTRUCTIONS Before Using the Sink BULL Before using the assembled Sink BULL be sure to complete the following preparations. Supply the Specified Voltage Supply the voltage specified on the nameplate of the grinder. Otherwise damage could result to the machine, or increase the risk of personal injury. Install a Ground Fault Circuit Interrupter (GFCI) WARNING: To prevent electrical shocks, be sure that the power circuit being used is protected by a GFCI device, or be sure to install the supplied ground fault circuit interrupter (GFCI) between the main power supply and the cord of the machine. Keep Water Out of the Grinder WARNING: Do not let water into the motor of the electric grinder. Water inside the machine will weaken the electrical insulation of the motor and may result in electric shock. Ensure the splash guard angle is installed at all times during use (see Figure 4). Organize the Work Area for Safe Operation Before beginning operations, make sure that the work area conditions are well organized for safe operation of the Sink BULL. Use Proper Safety Gear To prevent damage to eyes from flying debris, wear protective glasses or face shield. Be sure to wear waterproof safety boots, appropriate hearing protection and dust protection as required. How to Operate Overview 1. Creating a perfect cutout for an undermount sink is a multi-step process. The Sink BULL helps simplify this process and reduces the skill level required to quickly achieve excellent results. 2. Follow these basic steps to produce the perfect sink cutout: a. Drop the center of the sink hole with an appropriate saw. b. Rough grind the hole to shape with the Sink BULL and the Rapid Z -CUT grinding wheel utilizing a simple, inexpensive, shop made template. c. With the template still clamped in place clean up the hole with the Sink BULL and the COARSE Rapid Z -DRUM or other vacuum brazed drum wheel. d. With the template still clamped in place finish smoothing the hole with the Sink BULL and the FINE Rapid Z -DRUM. e. Remove the template and polish the edges of the cutout. Page 10

11 Grinding Wheel Selection 3. For the first rough grinding step (step b. above) we supply our Rapid Z -CUT - a 3 stacked blade Z wheel. This grinding wheel has 12 stacked diamond blades, and a bearing mounted stainless ring to ride against the template. It was specifically designed for use with the Sink BULL. The blades grind quickly and can be rearranged easily to correct apple coring for maximum blade life. When they are completely worn out the blades are inexpensive to replace. The template follower ring incorporates a two stage design to help compensate for blade wear (see Figure 9). Other grinding wheels may be used but have not been tested by NSI Solutions LLC. 4. For the second and third grinding step (step c. and d. above) we supply our Rapid Z - DRUMS two 3 Vacuum brazed drum wheels (COARSE grit and FINE grit) with top mounted bearings to ride against the template. This 3 diameter version will accomplish most work but a 1 diameter version will be required for tight corners and are available for purchase separately. The Rapid Z -DRUMS are sized to work in sequence with the Rapid Z -CUT. Each leaving a small amount of material to be removed with the next tool. The FINE grit drum produces a ready to polish surface flush to the template. The Rapid Z -DRUMS are reversible to extend tool life and when completely dull the drum portion is inexpensive to replace. Additionally the height of the Rapid Z products have been matched so that height adjustment between grinding tools is not required. Page 11

13 Rough Cut the Hole 1. Set your work piece on the work bench and secure it using appropriate clamps if required. 2. Using your template, trace the sink profile onto the stone at the correct location. 3. Remove the bulk of the sink cutout with a saw and appropriate blade as close to the line as feasible. Multiple types of saws can be used depending on the size and shape of the sink cutout. A Small, water feed, circular saw, a bridge saw/core bit combination, or a blade mounted on an angle grinder are popular options. 4. Take precautions to support the cutout so it does not drop when the cut is complete. Setup the Sink BULL 5. Install the Rapid Z -CUT grinding wheel or other appropriate initial grinding wheel onto the Sink BULL. The grinder has an arbor lock to aid installation and removal of the grinding wheel. 6. Connect the Sink BULL to a garden hose. Make sure the valve on the Sink BULL is off and turn the water on at the hose bib. 7. Plug the Sink BULL into a GFCI protected outlet or use the GFCI adapter provided. CAUTION: Follow all instructions and safety precautions provided with the Rapid Z -CUT and Rapid Z -DRUM and follow all manufacturer s instructions and safety precautions for any other grinding wheels used. CAUTION: Ensure grinder remains connected to a GFCI protected outlet at all times when in use or that the grinder is plugged into other GFCI protected circuit. Clamp the Template in Place 8. Place the template over the rough cutout and align it to the previously traced line. 9. Clamp the template in place with C-clamps. Two clamps are usually sufficient. Place the clamps at the corners of the template. Page 13

14 Initial Grinding/Shaping 10. Place the Sink BULL onto the template, spanning the hole, with the Rapid Z -CUT grinding wheel inside the hole. 11. Adjust the height of the grinder until the bearing is riding on the template and the grinding wheel is removing the stone (see Figure 10). 12. Turn on the water valve and adjust the nozzle to spray a sufficient fan of water onto the side of the grinding wheel. Ensure plenty of water is used. If you are creating dust during grinding, then more water is required. 13. Start the grinder and lock the switch in the ON position. 14. Pull the Sink BULL into the template until the bearing is riding against the template and work the Sink BULL back and forth grinding the cutout to the shape of the template. This is accomplished when the bearing is riding on the template and no more stone is being removed. Work the Sink BULL back and forth until the cutout is ground half way around. The Rapid Z -CUT will leave a small amount of material for removal with the COARSE Rapid Z - DRUM 15. Turn off the power and the water. 16. Pick up the Sink BULL and lift it over the C-clamps to the opposite side of the cutout. 17. Complete the rough grinding of the remaining half of the cutout moving the C-clamps to new locations if required. 18. Turn off the power and the water.

15 Final Grinding/Shaping 19. Unplug the grinder from the power supply. 20. Replace the Rapid Z -CUT with the COARSE Rapid Z -DRUM or other vacuum brazed drum wheel, approximately 40 grit. 21. Adjust the height of the grinder as required so the bearing rides against the template. If NSI Solutions Rapid Z products are used the height will not have to be adjusted since they are all designed specifically for use with the Sink BULL 22. Plug the grinder back into a GFCI protected power supply. 23. Repeat steps 12 through 19 above. The COARSE Rapid Z -DRUM will leave approximately.020 (.5mm) of material proud of the template. The cutout could be polished after this step but cleaning it up further with a fine drum will yield an easier to polish edge. 24. Replace the COARSE Rapid Z -DRUM with a FINE Rapid Z -DRUM (approximately 120 grit) and repeat steps 12 through 19 above except this grinding wheel will leave the edge of the cutout flush with the template and smooth enough for easy polishing. 25. After all grinding is complete; remove the Sink BULL and template. The cutout is ready to polish.
